new and useful Improvements inlAutomatic l-lasp`-Locks,of `vvhich the `following is a" specification.

l This `invention relates to improvements in locks, and especially to loeksof` the hinge` `or hasp` type in which `the look `case is mounted on a hasp and maybe moved there-` stationary mem-` `with toward and from a` ber such as a staple. p u l One objeetof the invention; 1s to provide an" improved hasp lock of thistypevvhich is adapted to be used on mail sacks, Oron heavy straps used ior baggage, hampers,

- l bowed member to hereinafter `described :and claimed.

Another object of the invention is to effect `improvements 1n the construction of the` bolt, and in which the bolt comprises a key `operated member and` a locking member l which 1s` movable` with the key operated" member to` one position, in one direction, and in which each of` said members, y, 1s mf pendently moving the said members` member to release position', Vand `also emlbodying a spring detent to normally `:hold

said bolt member in initiallpositiomand a@ `key for 1 use in.` releasing the deteut from the bbowcd `memberqaud `for also enabling the.`

be manually moved tol` req lease; position. 1

1 My improved :lockisz hereshovvn as arranged 1forluseon mail sack. The hasp `which forms one 1. sideof` the lock case 2' lshflnged as at` toa plate or bar` 4, which plate or bar 1s secured asby means of riv l plate or bar and is `arranged to `bepassed *through a `slot 10 `near the 4free end oi the strap and to be alsopassed through` a; slot 11 in thehasp and` to enter the flock case, wbenlthe'lhaspis closed. The. free end of the strap is hcreyshownas reinforced by a beveled sheet metalstrip 11 which is` riveted thereto and is arranged Son opposite The lock easeV provided in its out-er `side` with a keyhole slot` l2and alsogvvith `broadened end of` thekey `hole slot. ,l The bolt comprises a keysoperated member 14 and a locking member 15, the said members ..beingjarranged `for longitudinal movement in the lockicase andthe memberlfl having akey holewl. Saidmember is also `pro- "videdlon one sidevith ash'oulder 118.. `Detcnt springs `19,yvvhichj are secured at one ndfas at 1,7, to onefside ofi the lockcase,

" are arranged to; engage at-their` freecends on one side of the member 14, and against the,shouldenl (to,llockidthelmember 14 1n p The slot lpermits the member p y eylafagainst the tensionlof a spring 241, after the keyhas been turned a sufficient distance: to disengage the detent 19 from the stop shoulder 18, The member" 15 in the p locking member, is arranged at one end of "the member 14.- `and has a recess 21 in the fend which is opposed tothe member 14, to

receive the staple or stationary member `9', ivhen. the hasp `is closed, said member 15.also` `havirrga lug 22to engage the sta le and thereby lockthe hasp in closed posit on, and hln-ice' alsoy leek and firmly essere the strap A`tombe manually;V movedwzbyl `the i.

able in one direction by the spring 24, enables the devicefto be locked by simply closing the vhasp against the bar or plate after the free end'ofthe'strap'has beenengaged With the staple. Such closingof the hasp causes the vstaple to enter the lock case and strike the 'cam face of the lug 22 and thus Vcause the member toinove first against the tension of the spring 24 a suiiicient distance to clear the outer end of the "staple, the said spring then moving the'member 15 in the reverse direction, as will be understood, and engaging thev lug` 22 under'the outer end of the staple. "When it is A desired to unlock the device, the keyis inserted in the key hole 12, 16 partly turned a sufficient distance to dis` engage-the detent springs 19 fromthe shoulvderflS and is then employed to enable the member 14 tobe manually moved against ythe tension ofthe spring 24, such movement :of the member 14 'causing said member to push'member 15 against the tension of the spring 24 andto fdisengage the lug 22y from the hasp. staple.

The key may be of any suitable construe-- tion, and any suitable number of the detent` springs 19 may beemployed, The `lock case may be secured to the staple by any suitable fl' Gonieslof this patent may befobtainedfforf ve' cents each, by addressing the Gommissionerof Patents, l l Washington, D'. 0.,

means and the yvarious parts of the lock andY maybe made of any suitable ma' While I have herein shown and describedl vvtheprefe'rredl form of my invention, I would` have itiuiderstood Y,that changes maybe made inthe "form, proportion and construcv' tion oftheseveralparts, Without departing from thespirit of my invention,- and Within the scope of the vappended claims.

o i' the class described, a casing j having` a key hole and a slot forming an ex Vtension ot the key hole 5 a locking member movable in the `easing and comprising a key operated member and a locking member, said locking member being movable by the key operated member in one direction, a spring to Wlcpendently move the said members in the reverse direction, a spring detent to hold the key operated member in initial position, and a key, engageable with said member to release the detent, and also movable manually in theslot of the casing to move said key operated member against the tension of the spring and thereby cause the locking member to also be moved against the tension of its spring.

' 2.111 a lock of the class described, a casing having a key hole and a slot forming an extension of the key hole; a locking member movable in the lock and comprising a key operated member and a locking member, said locking member having a springr bolt and being movable independently of the key operated member to engage a staple or the like and being' movable by the key operated Vmember in one direction, a spring'to independently move thesaid member inthe reverse direction, a detent to hold the key operated member in initial locking position, and a keyengageable with the last named member' to 'release the detent and also movable manually in the slot of the casing to move said key operated member against the tension of the spring and thereby cause the locking member to` be also moved against the tension of its spring into release position.

8. A- lock of the class described, a staple, a lock having a casing hingedly mounted for movement toward and from the Staple, a spring actuated U-sliaped slide, a suitable engaging lug carried by the 'slide and a spring actuated key operated member movable' within the casing and spaced from the staple engaging lug and contacting with the U-shaped slide, whereby the latter may be independently moved through Contact of the staple with the staple engaging lug to lock the lock or operated bythe'movement of the key engaging member to release thestaple.

In'testimony whereof I aiiix my signature.
